Abstract

Primary biological aerosol particles (PBAPs) are involved in multiple phenomena ranging from seasonal allergies to pandemic diseases. Furthermore, PBAPs that act as ice nuclei, might interact with cloud physics affecting the formation of hail and, potentially, causing damage to agriculture. These latter dynamics are still unclear, especially due to the lack of knowledge about PBAPs concentration and emission rates. Here we characterized the fungal aerobiology of Arceburgo, Minas Gerais State, Brazil, through ground level and airborne sampling of PBAPs via a hot-air balloon. Total and cultivable fungal spores were collected using personal portable Burkard and a MAS100 sampler respectively during the summer and winter of 2019. In the latter season, daily dynamics were resolved by repeating flights and sampling in the morning and in the afternoon. Both samplers identified a core fungal community (Penicillum/Aspergillus and Cladosporium spp.) that are coupled with local meteorological dynamics and are able to undergo atmospheric transport as indicated by their survival in the night-time residual boundary layer. These results are invaluable in identifying a core set of aerobiological indicators that can be used in future works to unravel PBAPs emission rates on the area of Arceburgo and form a basis to close the gap in knowledge in the interplay between PBAPs and hail formation.

巴西米纳斯吉拉斯州生物气溶胶垂直真菌孢子剖面

初级生物气溶胶颗粒（PBAP）涉及从季节性过敏到大流行性疾病的多种现象。此外，PBAP作为冰核，可能与云物理相互作用，影响冰雹的形成，并可能对农业造成损害。后一种动态仍然不清楚，特别是由于缺乏对多溴联苯醚浓度和排放率的了解。在这里，我们通过热气球对多溴联苯醚进行地面和空气采样，对巴西米纳斯吉拉斯州Arceburgo的真菌空气生物学进行了表征。在2019年夏季和冬季，分别使用个人便携式Burkard和MAS100采样器收集了总真菌孢子和可培养真菌孢子。在后一个季节，通过在上午和下午重复飞行和采样来解决日常动态。两个采样器都确定了一个核心真菌群落（青霉/曲霉菌和枝孢霉属），该群落与当地气象动力学相结合，能够通过在夜间残留边界层中的存活来进行大气迁移。这些结果对于确定一组核心的空气生物学指标是非常宝贵的，这些指标可用于未来的工作，以揭示Arceburgo地区多溴联苯醚的排放率，并为缩小多溴联苯和冰雹形成之间相互作用的知识差距奠定基础。

期刊介绍： Associated with the International Association for Aerobiology, Aerobiologia is an international medium for original research and review articles in the interdisciplinary fields of aerobiology and interaction of human, plant and animal systems on the biosphere. Coverage includes bioaerosols, transport mechanisms, biometeorology, climatology, air-sea interaction, land-surface/atmosphere interaction, biological pollution, biological input to global change, microbiology, aeromycology, aeropalynology, arthropod dispersal and environmental policy. Emphasis is placed on respiratory allergology, plant pathology, pest management, biological weathering and biodeterioration, indoor air quality, air-conditioning technology, industrial aerobiology and more. Aerobiologia serves aerobiologists, and other professionals in medicine, public health, industrial and environmental hygiene, biological sciences, agriculture, atmospheric physics, botany, environmental science and cultural heritage.
